I agree. Very interesting information.
Sometimes, I wonder about dogs. The very same animals that can eat roadkill and garbage, roll in the foulest smelling stuff they can find, drink puddle water and do just fine, turn around and wind up with sensitive stomachs for the expensive food we buy and put in their bowls.
I would never have thought about some of the stuff that you posted, Space Racer, and I must admit to being guilty of almost everything you posted about.
